IDG Contributor Network: How NFV and interconnection can help you think outside the ‘box’

Networking used to be all about specialized “boxes,” but that era is fading fast.  By a specialized box, I mean a piece of hardware that was built to perform an individual function. Physical firewalls, routers, servers, load balancers, etc., are all examples of these different boxes, and they are still everywhere. But new technology is seriously disrupting the old ways of doing things.Virtualization has made it possible to separate the software functionality of all those boxes from the specific appliance-type hardware in which it resides. Network functions virtualization (NFV) software can replicate an appliance’s function in a more cost-effective commodity server, which is easy to obtain and deploy and can hold the software for numerous functions at once. People like the improved simplicity, cost, agility and speed that comes with this change.To read this article in full, please click here

New in IPv6: Stable Random IPv6 Addresses on OpenBSD

The idea of generating random IPv6 addresses (so you cannot be tracked across multiple networks based on your MAC address) that stay stable within each subnet (so you don’t pollute everyone’s ND cache every time you open your iPad) is pretty old: RFC 7217 was published almost exactly four years ago.

Linux was quick to pick it up, OpenBSD got RFC 7127 support a few weeks ago. However, there’s an Easter egg in the OpenBSD patches that implement it: SLAAC on OpenBSD now works with any prefix length (not just /64).

BrandPost: SD-WAN: A Modern Approach to Connectivity for Digital Businesses

Digital transformation has crossed the chasm from visionary aspiration to practical implementation and in the process, it is disrupting technologies across the business landscape.As enterprises and governments transform their operations, many are finding their legacy wide area networks (WANs) cannot meet today’s digital-driven bandwidth demands. Rather than giving them a competitive edge and supporting business growth, their networks are stifling innovation and impeding flexibility.To address this challenge, software-defined WANs (SD-WANs) are emerging as a smart way to streamline connections among enterprise sites.Enterprise WANs are under pressure to keep pace with the cloud revolution, which plays a critical role in digital transformation. “Companies worldwide are aggressively consolidating their data centers, implementing new data models, and shifting development to agile, mobile-first, cloud-based models,” IDC Group Vice President and IT executive advisor Joseph Pucciarelli writes in the Winter 2018 Issue of CIO's Digital Magazine.To read this article in full, please click here

Using Travis CI (Continuous Integration) with GitHub

Hi ,

Am Planning to write a in detail usage of how we can leverage
Aws cloud - ansible - github - travis-(ci/cd) with in our networking 
deployment space. As of now, I will quickly author how you can 
leverage the usage of Travis CI in our 
experimental space. 

You can find more about Travis CI - Here - .org of travis will 
help to run Opensource Projects 

https://travis-ci.org/

I am using AWS cloud desktop to do the changes to the code, 
get it pushed to git-hub and then integrate everything 
if Travis CI passes the checks 

To let you know the workflow in a very simpler way 

-> You write any code or config related to networks on AWS cloud 
desktop
-> push the code into git-hub in a branch later to be integrated 
into Master Branch
-> Setup Travis to automatically run some pre-defined tests 
-> If all successful, we will merge the code into our master branch 

-> Lets write a very basic code in a branch and push to git-hub 

 




The github page has been integrated with Travis-CI 

 




Travis CI peforms the required checks, here it just 
checks for syntax, obvious this can be exetended  Continue reading

Wireless ESSID as ROT13 Ciphertext

Recently, I have scanned nearby wireless networks with airodump. I have discovered five networks transmitting on channel 3. MAC addresses of access points (BSSIDs) transmitting on channel 3 differ only in last two hexa digits and a signal level (PWR) reported by my WiFi card is almost same for all BSSIDs.

$ sudo airodump-ng wlp3s0

Picture 1 - Wireless Networks of Caffe Geo Guru

The following three ESSIDs have caught my attention.

1) Heslo do siete caffe.geo.guru
2) zistis rozlustenim sifry
3) qnw fv qboer cvib

In fact, the ESSIDs represent a cryptography challenge created for customers of caffe.geo.guru. Once the challenge is successfully solved a customer gains a password for connection to the wireless network with ESSID caffe.geo.guru.

Note: The first two ESSID are written in Slovak. Their English version is below.

1) Password to network caffe.geo.guru
2) can be gained by decoding words
3) qnw fv qboer cvib

The third ESSID represents an encoded password. Obviously, letters are substituted in ciphertext which let us to the assumption that ROT cipher is used. Using ROT13 cipher on the encoded text 'qnw fv qboer cvib' gives us a required plain-text password Continue reading

Worth Reading: Model driven telemmetry

Telemetry is a big buzzword in the networking industry these days. As any buzzword, telemetry means different things to different people; exactly like SDN or intent-based networking (I guess this one will need its own blog entry at some point in time). —Benoit Claise

Get Smarter About Container Monitoring

Deconfusing the Static Route

Configuring a static route is just like installing an entry directly in the routing table (or the RIB).

I have been told this many times in my work as a network engineer by operations people, coders, designers, and many other folks. The problem is that it is, in some routing table implementations, too true. To understand, it is best to take a short tour through how a typical RIB interacts with a routing protocol. Assume BGP, or IS-IS, learns about a new route that needs to be installed in the RIB:

• The RIB into which the route needs to be installed is somehow determined. This might be through some sort of special tagging, or perhaps each routing process has a separate RIB into which it is installing routes, etc.. In any case, the routing process must determine which RIB the route should be installed in.
• Look the next hop up in the RIB, to determine if it is reachable. A route cannot be installed if there is no next hop through which to forward the traffic towards the described destination.
• Call the RIB interface to install the route.

The last step results in one of two possible reactions. The first Continue reading

Digital Empowerment of Women in South Asia

The Internet Society Pakistan Islamabad Chapter (PK IBD) organised a webinar on “Digital Empowerment of Women in South Asia” on 15 March, 2018. ISOC Chapter leaders, members, and staff participated in the webinar where the regional and global women-centric initiatives were shared by the speakers.

The undersigned welcomed the audience on behalf of the Internet Society Pakistan Islamabad Chapter followed by a round of introductions. Joyce Dogniez, the Internet Society’s Senior Director, Global Community Engagement, shared the importance and relevance of the UN-EQUALS partnership which is a unique collaboration between state and non-state actors to bridge the digital gender divide. Joyce shared that the Internet Society is an important part of this partnership that primarily emphasizes improving ICT access, imparting digital skills, and promoting leadership of women. Internet and digital literacy leads to economic empowerment of women that can have a profound community impact.

The next session featured updates from the Chapter Leaders of South Asia on the various initiatives being undertaken on the country and Chapter level. Sagarika Wickramasekera from the ISOC Sri Lanka Chapter informed about the initiatives of the Chapter including WomenIGF, IT trainings for girls at school level, Internet learning programmes for women entrepreneurship, etc. Sidra Jalil from Continue reading
